Hong Kong Faces Severe Weather Amid Ching Ming Festival

On April 4, 2026, the Hong Kong Observatory issued an amber rainstorm warning due to intense thundery showers influenced by a trough of low pressure. The warning, which indicates heavy rain exceeding 30 millimeters per hour, was first announced at 11:00 AM and extended until 2:30 PM. The Observatory noted that heavy rainfall was particularly severe in the Tai Po district, raising concerns about potential flooding in low-lying and poorly drained areas.

The heavy downpours prompted emergency responses, with rescuers dispatched to assist hikers who became stranded due to the adverse weather conditions. Notably, an elderly couple, aged 76 and 68, lost their way on Tai To Yan, a challenging ridge in Tai Po, and required assistance at 11:47 AM. Firefighters successfully rescued them without injuries. Similarly, three hikers on Yuk Kwai Shan in Ap Lei Chau also needed rescue around 12:31 PM, highlighting the risks posed by the severe weather.

Looking ahead, the Observatory anticipates continued rain and thunderstorms on Sunday, with expectations of improving weather conditions later in the week. The trough of low pressure affecting the region is predicted to weaken, leading to brighter weather by midweek.

While the amber rainstorm warning is the lowest in Hong Kong's three-tiered warning system, some residents expressed concerns about the adequacy of the city's infrastructure to handle such severe weather events. Critics argue that more proactive measures are needed to mitigate flooding risks, especially during significant public events like the Ching Ming Festival.

There are discrepancies regarding the exact rainfall measurements, with some reports indicating over 70 millimeters per hour in certain areas, while others cite lower figures. This variation underscores the challenges in accurately assessing weather impacts in real-time.
